The control extends the behavior of ASP.NET server controls with additional JavaScript on the client side and also server side.


It provide simplicity in select the date from month. It contains main key properties: TargetControlID and Format.

How we implement the CalendarExtender


Step1: we use the following control on aspx page




    <form id="form1" runat="server">


<%--Using ScriptManager or ToolkitScriptManager according toolkit version--%>

    <asp:ScriptManager ID="ScriptManager1"runat="server"></asp:ScriptManager>

    <%--using textbox--%>

    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

    <%-- using calenderextendar here--%>

    <cc1:CalendarExtender ID="CalendarExtender1" runat="server" TargetControlID ="TextBox1" Format="MMM/dd/yyyy">






Step2: Run the project

       Press the mouse button on textbox


                    Select the date from calendar


This is the simple demonstration of CalendarExtender in the web application.
